Preparing for an IUD insertion is mostly about small, practical steps that can make the experience smoother and less painful. The procedure itself takes only a few minutes, but what you do in the hours before your appointment can genuinely affect how it feels. Here’s what to know and what to do.
Take Ibuprofen One Hour Before
The single most consistently recommended preparation step is taking 800 mg of ibuprofen about one hour before your appointment. This is the standard guideline for IUD insertion pain management, and it’s the only oral pain reliever with a formal recommendation behind it. That’s four over-the-counter 200 mg tablets. Take them with food to avoid stomach irritation.
If you can’t take ibuprofen due to allergies or stomach issues, let your provider know ahead of time so they can suggest an alternative.
Ask About Numbing Options
Some providers offer a local anesthetic injection at the cervix, called a paracervical block, before placing the IUD. In a clinical trial comparing this block to no block, women who received the numbing injection reported significantly less pain during insertion, during the measurement of the uterus, and five minutes afterward. Their overall perception of pain for the entire procedure was also lower.
There’s a tradeoff: the injection itself causes some discomfort. But for most women in the study, the temporary sting of the block was worth the reduced pain during the actual placement. This option is more commonly discussed for people who haven’t had a vaginal delivery, since the cervix tends to be tighter. Not every clinic offers it routinely, so call ahead and ask if it’s available.
You Don’t Need to Time It to Your Period
You may have heard that you should schedule your insertion during your period. Some providers prefer this timing because menstruation provides reassurance that you’re not pregnant, and the cervix may be slightly more open. But a CDC-funded systematic review found that the timing of insertion within your menstrual cycle has little effect on pain, bleeding, expulsion rates, or how long you end up keeping the IUD. Schedule your appointment for whenever works best for you. If your provider needs to confirm you’re not pregnant, they can do a quick urine test at the office.
What Happens Before the Procedure
Most people don’t need extensive medical testing before an IUD insertion. The CDC classifies a bimanual exam (where the provider checks the position and size of your uterus by pressing on your abdomen and inserting fingers into the vagina) as essential for copper IUD placement. For hormonal IUDs, even this exam is classified as less critical, though most providers still perform one.
STI screening is not required for everyone. If you have risk factors for sexually transmitted infections and haven’t been recently screened for chlamydia and gonorrhea, your provider may test you at the same visit. Importantly, this screening doesn’t delay placement. The IUD can go in the same day, and if results come back positive later, you’ll be treated then. The only exception is if you have an active, visible infection at the time of your appointment.
Eat, Hydrate, and Dress Comfortably
Eat a normal meal and drink plenty of water before your appointment. Showing up on an empty stomach increases the chance of feeling lightheaded or dizzy during the procedure. Some people experience a vasovagal response, a sudden drop in blood pressure that can cause nausea, sweating, or fainting. Having food in your system helps your body handle the stress of the moment.
Wear comfortable, loose-fitting clothing, particularly bottoms that are easy to take off and put back on. You’ll be undressed from the waist down during the procedure. Bring a pad or panty liner with you, since light spotting or bleeding afterward is common. Some clinics provide pads, but it’s worth having your own just in case.
What to Expect During Insertion
Knowing what’s coming can make the experience feel more manageable. The provider will insert a speculum to open the vaginal walls, the same device used during a Pap smear. Next, they’ll use a tool called a tenaculum to gently grip and stabilize your cervix. This is the step that catches many people off guard. The tenaculum has small hooks that lightly puncture the cervical tissue to hold it steady, and it can cause a sharp pinch or cramp.
After that, the provider measures the depth of your uterus using a thin instrument called a sound. This part often feels like a deep, sudden cramp. Finally, the IUD itself is placed through the cervix and into the uterus using a slim insertion tube. The whole process, from speculum to IUD placement, typically takes under five minutes. The most intense sensations last only seconds, though cramping can linger afterward.
Plan for Mild Downtime Afterward
Most people can drive themselves home and return to normal activities the same day. That said, it’s smart to have a backup plan. Some people feel significant cramping, dizziness, or general unsteadiness after the procedure. If you can, bring someone along to drive you home, or at least plan to sit in the waiting room for 10 to 15 minutes before getting behind the wheel.
Cramping in the hours and days after insertion is normal, especially with the copper IUD. A heating pad and continued use of ibuprofen can help. Light spotting or irregular bleeding may continue for a few weeks as your body adjusts. Many people find it helpful to keep their schedule light the day of the appointment, even if they end up feeling fine.
Know Your IUD’s Lifespan
Part of preparation is understanding the long-term commitment you’re making, which varies by device. Mirena and Liletta are approved for up to eight years. Kyleena lasts up to five years, and Skyla up to three. The copper IUD, Paragard, is approved for up to ten years. When your IUD reaches its expiration, your provider can remove it and place a new one in the same visit if you’d like to continue.
Before your appointment, it’s worth thinking about which IUD you want and why. Hormonal IUDs tend to lighten periods over time, and some people stop getting periods altogether. The copper IUD contains no hormones but can make periods heavier and crampier, particularly in the first few months. Your provider can help you weigh the options, but arriving with some baseline knowledge makes the conversation more productive.
